Bias tape is often used to neaten the arm hole and neckline, either concealed or for decorative purposes. While craft stores are well stocked with a wide variety of colours, sometimes they just do not match the colour of your fabric. At times like this, I make my own bias tape. It is a very simple process.
1. Decide on the width of the bias tape and purchase the bias tape maker of the correct size. The standard size is about 12mm. I bought mine from the local craft store, and the brand is Clover. This range of tape makers have 5 different widths: 6mm, 12mm, 18mm, 25mm, 50mm.
For my piece, it is a piece of scrap fabric from my half circle skirt which is cut on bias. So i trimmed off the excess to neaten the ends to get a triangle.
I’m assuming that the piece of fabric has sufficient to produce the length you want. If not, you can always sew and connect stripes of them on the bias ends.
4. Feed the strip of fabric, with the wrong side facing you, into the broader end of the bias tape maker. It is easier to feed the fabric into the maker if the fabric has a 45° pointed end, rather than a 90° end.
7. Trim off the pointy ends.
